This tutorial was translated with PSPX7 but it can also be made using other versions of PSP.
Since version PSP X4, Image>Mirror was replaced with Image>Flip Horizontal,
and Image>Flip with Image>Flip Vertical, there are some variables.
In versions X5 and X6, the functions have been improved by making available the Objects menu.
In the latest version X7 command Image>Mirror and Image>Flip returned, but with new differences.
